The PureGuardian 1.5 Gal. Warm and Cool Mist Ultrasonic Humidifier is an impressive device that offers a blend of functionality and convenience. Its 1.5-gallon tank is a standout feature, allowing the humidifier to run for two to three nights without needing a refill, even when used for approximately nine hours each night. The humidifier offers versatile features, including three levels of humidification, UV light to sanitize water, and a soothing LED light that can either cycle through colors or remain fixed on one. The scent diffusion option adds a nice touch, although it’s slightly disappointing that essential oils cannot be added directly to the water. Overall, the humidifier provides excellent performance and thoughtful features, making it a solid choice for maintaining comfortable indoor air quality. On the downside, the humidifier does have some minor inconveniences. While the large tank is a benefit for extended use, it can be unwieldy to handle when full, making it tricky to load back onto the base. Additionally, the bright indicator light on the front can be distracting in an otherwise dark room, especially for light-sensitive sleepers. It’s unclear if this can be adjusted, and I plan to revisit the manual to check for solutions. Despite these drawbacks, the PureGuardian humidifier remains a reliable option that effectively balances functionality with ease of use.

I turned it on the humidity was 33 percent. I turned it on automatic 40 percent setting it ran silently for around 12 hours and shut off at 41 percent only used a third of the tank. Love how you can see the steam flowing from the top. Also no pad to worry about. And not noisy like our old one.

A wonderful product, easy to use and puts out a good amount of mist, whether cool or warm.

This is a mighty and compact humidifier that works great and has a few different settings. Very convenient and easy to use. Recommend the colds and flu are setting in this time of year when everyone is ill.

I purchased last year for the winter. I used it a handful of times and was great. I went to use it for the season and now it's leaking between the base and the tank. Mind you, this humidifier has been used a total of maybe 10 hours. It had great potential and I loved it while it worked, but it's useless to me now.

I love the fine mist and that you can set the humidity %. I don't even hear it running.

It does the job. The only reason i gave it 3 stars is due to the fact that there is no warm mist. They advertise this but it is false. The warm mist option gives you the same old cool mist. If you want a warm mist option, do not buy this.

Love the cool mist, holds lots of water at a time, works great!

Helps to breathe so much better

Easy to use. Very fine mist. Good design.
